' 'To all wliom it may concerns Be it known tliatlp'Dxrunn L. HOLDEN, a citizen 1 of 'rejs'idin'gat' New York, in the -c ounty of New YorkandhS tateofQNeW York, have invented certainnew and useful Improvements in Freez- "ing-Machines for Ice Manufacture, of which the followingis aspecification. I, I The object of,.this invention is to construct a machine for the rapid productio'nof ice particles to be used in aregeling process, There are arranged mul-" tiple pairs of horizontally rotatable freezing cylinders in a clear water tank, with means to, chip fromthe'adsjacent surfaces of each pair of cylinders their adhering ice coats, in minuteparticlesyto convey the particles to the center of the tank, under a dome over each pair 1 of eylinders which has, at its apex, a connection toa pump (not shown) which sucks up ,the ice particles and .passes them to presses where they are pressed and regeled into blocks of merchantable size. It must be understood that the cylinders arecharg'ed with freezing material; that multiplepairsof cylinders are employed to insure a great output; that for smaller capacity plants a singlepair of cylinders, or even a single cylinder lnight supplytheneeded quantity of ice particles, using the same methods as shown,

The invention is illustrated in the accompanying drawings in which similar'reference' characters apply to" and designate the same parts,'wherever shown, in which Figure l is a section of the tank with a freezing cylinder rotatably located therein, with the right and the ice particles from the cylinders. Fig. 3 is a lon-, 3

gitudinal elevation of a freezing cylinder and the means for chipping the adhering ice from its surface. Fig. 4 is an end view of a chippingroller. Fig. 5 is a fragmentary elevation-of a chipping roller. Fig. 6 shows the freezing cylinders as arranged in pairs, in

a tank, with a dome central over their adjacent sides,

with their screws, chipping rollers and hoods.

Within a suitable tankl cylinders 2, 3, 4, 5 are 'mounted on.bearings. 6, 7 for rotary movement, the

cylinders being arranged in pairs, and as many duplications oi the pairs of cylinders may be employed as .are necessary to furnish the quantity of ice particles which will adequately supply the presses (not shown) of a complete equipment. The cylinders; are rotated I by'a chain on the sprocketiwheel 8, or by other suitable means.v Between, each pair of cylinders there are mounted a right and a left screw 9, 10 in bearings 11,12

with a sprocket wheel 13, or equipment means, to rotate the screws, and to thereby force the particles to the ticlesfrom the. tank. a the adjacent'sides of each pair-or" cylinders, and

in contact therewith, there isa chipping roller 18 having journals 19 in levers 20' pivotallj secured at their opposite ends to lugs 21 attached to tank 1. .Intermediate thejoumals 19 and lugs 21 brackets 22 are secured to tank 1 and carry adjusting rods having center of the tankj'under domes 14, 15 which are p'r I videdwith a pipe 17 which communic'ates with a pump I,(n'ot shown) which by-suction removes the ice para screw threaded portion 23 and a jaw 24 to embrace v ness of th e ice coating on thecylinder. The rotation oi the cylinder rotates the roller in an opposite direction, by contact with the ice coating, and the spicular surface of the roller, as seen in Figs. 4, 5, removes the ice coating in minute particles. In order to still further assure the removal of every particle of ice, additional rollers, 28, of smaller diameter are provided, and adjustably suspended independent of rollers 18,

by levers 29 secured between jaws 30 of levers 20 and over journals 19, the outer ends of levers 29 enter jaws 31 of suspension rods 32, the rollers 28 having journals 33 in jaws, 31 and levers 29, the rods 32 having nuts 34 similar to the nuts for rods 23, these nuts being secured in brackets 35 on tank 1. Pinions 36 are secured to journals 19, pinions 37 are secured to journals 33, and intermediatepinions 38 are secured to studs 39 in levers-29, the pinions insure the positive rotation of rollers 28 by rollers 18, in the same direction, and the independent suspension 'of rollers 28 assures their proper alinement to follow the cylinders surface and its ice coating.

Above screws 9, 10 there are hoods 40,141 to catch the ice particles as they float away from the cylinders and chipping rollers, prevent them from floating to the surface oi-the water in the tank and away from i the screws. The hoods are semicircular at their tops with perforations 42, for free water circulation, and have outwardly fiaring sides extending beyond the chipping rollers, so that all ice particles are held for the screws to convey them to'the center oi the tank, under a dome, where they are immediatelysucked up and conveyed to the presses. By arranging the cylinders in pairs, rotating them in reverse directions,

and chipping the ice particles in close proximity, and underneath the screws and their hoods, the ice particles are certain to be taken to the center of the domes, and to the pipes which convey them away, without floating upon the surface of the water in the tank where they are liable to lodge at the lower part of the domes; the sides of the domes are 'also made steep to avoid the liability of a lodgment of the ice particles.

I claim. I

1. In an ice machine, a freezing tank, a series of r0- tatable freezing cylinders therein, in. pairs, chipping rollersv suspended to engage each cylinder, located between each pair of cylinders and rotatable by the cylinders but in opposite directions, a second rotatable chipping roller named roller, and in the same direction, but in an oppositc direction to its freezing cylinder. 5

2. In an ice machine, a freezing tank, rotatable freezing cylinders submerged therein, a pair of chipping rollers adjustably suspended to engage each cylinder, means for the rotation of one of the rollers by its freezing cylinder,
